Last week I used my iPhone as an ipod in an airplane, using a Sony headphone with a self adjusted (cut-off some plastic) connector to fit in the iPhone.
when going out of "airplane mode" took out my Sony headphone, my iphone muted all the way, no speaker nothing ...no audio.

I had to plug in and out the original headphone to get i working again.

Anyone had this problem? Any solution?

Thanks.
